MARTIN FEDDERS, OF MASURY STATION, OHIO.

FLYINGJIIACHINE.

Application filed April 13,

To all whom it may concern:

Be it known that I, MARTIN FEDDERS, citizen of the United States of America, residing at Masury Station, in the county of Trumbull and State of Ohio, have invented certain new and useful Improvements in Flying-Machines, of which the following is a specification.

This invention relates to air craft. The principal object is to device a machine provided with a regular propeller and in addition to this, two propellers energized by independent means. One of the independent propellers is located on the top and-near the front end of machine. The second independent propeller is located at the rear of the machine.

Another object is to provide means for moving the front independent propeller along a se ental rail, thereby g1V1I1g.thQ propellers aft a perpendicular position or approximately any angle between the perpendicular and 45.

A still further object is to provide means for tilting the rear independent propeller,

and also to cause it to move along a segmental rail when in a vertical or lateral position, or any de ree Within the tilting mean or extremes of t e segmental rail.

The drawing illustratesa referred embodiment of the invention. owever, it is to be understood that in adapting the same to meeting different conditions, various changes in the form, and minor details of construction may be resorted to without departing from the nature of the invention as claimed and set forth in the drawings:

Figure 1 is a side elevation.

Fig. 2 is a top plan view.

Fig. 3 is a detail view partly in section.

F ig. 4 is a detail view partly in section.

Fig. 5 is a sectional view taken on line A--A of Fig. 3.

Corresponding and like parts are referred to in the following description and indicated in the several views of the drawings by like reference characters.

By referring to Figs. 1 and 2 it will be seen that the machine embodies a hull or shell 1 which comprisesv a forward cylindrical portion 2 and a rear tapering portion 3. A bracket 4 is secured to the underside of the forward portion 2 and is provided with a rolling support 5. A trailing skid 6 is secured to the underside of the tapering 3, and acts jointly with the rolling support 5,

to sustain the machine when a surface as when alighting For proper steering, vided with rear rudders traveling upon or taking off.

the machine is pro- 7 and 8, the rudder 7 occupying a vertical position, and the rude der 8 being horizontally disposed. These rudders may be of any .conventional type and adapted to be manipulated by suitable operating means.

A cook the hull or shell 1 and is designed with view to assemble the operating levers of the various parts to be actuated.

For sustaining the machine during flight it is provided with laterally extending planes 10 which may be of conventional construction.

The machine is equipped with a conventional type of engine and designated as engine 11, which energizes the propeller 12.

The lifting and propelling blade 13 is energized by means of an electric motor 14, which in turn secures its current for men gizing same from a generator 15 which is in turn energized by. an independent motor 16.

In order to move the shaft 18 along the segmental rail 17, I have provided a hydraulic motor 19 (see F igs'.- 3, 4 and 5). This. motor 19 is secured to the shaft 18. This motor consists of two fluid gears 20 secured within a housing, one of said fluid gears 20 being provided with an extended shaft end 21 carrying a cog wheel 22 registering with the teeth on the segmental rail 17.

By referring to Fig. 5 it will be seen that the housing containing the fluid cars 19 has intakes or outlets'23 connecte with a pump 24, as indicated in .Fig. 1. The connection may be of a pliable hose type or of any other suitable construction.

At the rear end of the machine I have provided a bracket 25 secured to the body of machine. Firmly secured to this bracket 25 is a rod 26. At the outer ends of this rod 26 the ends of a segmental rail 27 are firmly pit 9 is located about medially of secured. A shaft 28 carrying an electric motor 29 similar to motor 14 energizes a blade 30. In order to move the shaft 28 along the segmental rail 27, I have provided a hydraulic motor 31 similar in every way with the motor 19 above described.

WVhen it is desired to use the blade 30 for lifting, I have provided an arm 34 to the bracket 25 which is coupled to a hydraulic cylinder 32 by means of a link 33. This hydraulic cylinder 32 is provided with a piston 35, Which is caused to act by means of a fluid pressure exerted as desired upon either side of a piston head of ordinary construction. The piston 35 is caused to move in or out, thereby tilting the segmental rail 27 and connected parts by pressure exerted by means of the pump 24 suitably connected to the cylinder 32.

It is apparent that by means of the tilt and side motion of the rear lift and propeller blade 30 the machine can be set so that if unbalanced, due to a broken end of plane, or side strain due to any cause the machine, canbe sustained in an upright position. Further that When the primary motor for any reason will not work, the secondary motor may be employed. Again when desired MARTIN FEDDERS.
